Specify an Object Snap
To specify an object snap at a prompt for a point, you can
When prompted for a point, right-click and choose an object snap from
the Snap Overrides sub-menu
Enter the name of an object snap at the Command prompt
On the status bar, right-click the object snap button
When you specify an object snap at a prompt for a point, the object snap stays
in effect only for the next point that you specify.
NOTE Object snaps work only when you are prompted for a point. If you try to
use an object snap at the Command prompt, an error message is displayed.
Use Running Object Snaps
If you need to use one or more object snaps repeatedly, you can turn on running
object snaps. For example, you might set Center as a running object snap if
you need to connect the centers of a series of circles with a line.
You can specify one or more running object snaps on the Object Snaps tab in
the Drafting Settings dialog box, which is accessible from the Tools menu. If
several running object snaps are on, more than one object snap may be eligible
at a given location. Press Tab to cycle through the possibilities before you
specify the point.
Click the object snap button on the status bar or press Fn-F3 to turn running
object snaps on and off.
NOTE If you want object snaps to ignore hatch objects, set the OSOPTIONS
system variable to 1.
Use Object Snaps in 3D
By default, the Z-value of an object snap location is determined by the object's
location in space. However, if you work with object snaps on the plan view
of a building or the top view of a part, a constant Z-value is more useful.
If you turn on the OSNAPZ system variable, all object snaps are projected
onto the XY plane of the current UCS or, if ELEV is set to a non-zero value,
onto a plane parallel to XY plane at the specified elevation.
